HIGH RESOLUTION 3D-RECONSTRUCTION OF BODY PARTS WITH STRUCTURED LIGHT ILLUMINATION

Keywords

Abstract

This paper describes a low-cost miniaturized 3D
reconstruction approach using structured light. By
projecting known patterns onto a surface shape and
structure of the surface can be measured and characteristic
parameters of deformation can be determined. Existing
approaches use large geometries and complex optical
components. Here we present our system with a size of a
cigarette pack and a working distance of only 6 cm. The
theoretical depth resolution of the system, estimated from
the camera and projector resolution and the system
geometry, is about 150 µm. The total costs for
components excluding PC and mount are less than
300 EUR.
